What is the warning of timer completion time approaching?
In Options, the “End point close warning time” is a configurable value that you can set, this allows you to issue a warning a number of minutes before the timer is complete. e.g. If you need to warm the plates for your dinner, if you wait till the timer is complete then you will be over cooking your dinner. By setting the end point close warning time and configuring a notifier to notify you you can then be prepared and warm you plates ready for your dinner.
